To guide clinical blood transfusion practices for pediatric patients, the National Health Commission has issued the health standard "Guideline for pediatric transfusion" (WS/T 795-2022). Blood transfusion is one of the most commonly used supportive treatments for children with hematological diseases. This guideline provides guidance and recommendations for blood transfusions in children with aplastic anemia, thalassemia, autoimmune hemolytic anemia, glucose-6-phosphate dehydrogenase deficiency, acute leukemia, myelodysplastic syndromes, immune thrombocytopenic purpura, and thrombotic thrombocytopenic purpura.

Immunologic thrombocytopenic purpura (ITP) is a condition that affects four to 18 per 100 000 children every year. In most cases, spontaneous remission occurs, but splenectomy may be proposed. Exploring the site of platelet sequestration can help to better predict potential poor responders to splenectomy, but In-radiolabeled platelet scintigraphy (IPS) can be difficult to perform in children with very few platelets.

In Immune-mediated Thrombotic Thrombocytopenic Purpura (iTTP), patients develop antibodies against ADAMTS13. The majority of patients exhibit inhibitory anti-spacer antibodies. Non-inhibitory antibodies binding to the carboxy-terminal CUB domains have been suggested to enhance the clearance of ADAMTS13 in iTTP.

Thrombotic thrombocytopenic purpura (TTP) is characterized by thrombotic microangiopathy resulting from decreased activation of the von Willebrand factor-cleaving protease (ADAMTS13). TTP can cause organ damage and is often fatal if the appropriate treatment is not started immediately. Although primary immune TTP is the most common form of TTP, secondary immune etiologies, including complications from immune checkpoint inhibitors (ICIs), have also been reported.
